Types of Lighthouses

Towers and Cottages
  • Towers and cottages were the first lighthouses in
    Chesapeake Bay.
  • Usually made out of stone or brick, and were
    built in viewing distance for ships.
  • Were used until the 1800s because they came up
    with a more efficient light source for the ships.
  • The oldest of this type is still lit in Maryland
    today.
  • Shore erosion damaged many of these lighthouses.

Screwpiles
  • Built between 1854-1900.
  • Built in with iron legs, which are stabilized
    into the bottom of the Chesapeake Bay.
  • Normally placed on mouths of rivers or shoals.
  • Because of manmade barriers against currents and
    high winds screwpiles were the best design.
  • 42 of this type were built in the Bay.

Lightships
  • First lightship was built in 1820, and the last
    was 1960.
  • Wooden sail powered vessels that were used as
    floating lights.
  • Were built to sustain harsh conditions that
    lighthouses would never be able to stand.
  • Mostly used in deep waters and shoals.
  • They soon became equipped with more advanced
    lighting and radio technology.

    sailors depended on lighthouses to warn them of
